refactor(mobile): finish shared task and inbox adoption

[richardsolomou]

Problem

Mobile still wraps canonical task/inbox types and keeps separate repository and inbox transport after adopting the shared task runtime.

Depends on #3637
Refs PostHog/posthog#76229

Changes

Phase 2: I finished the shared task adoption, migrated repository aggregation and inbox transport, and removed the replaced mobile helpers. This PR changes mobile consumers only.

How did you test this?

• Full monorepo typecheck at this checkpoint
• Final stack: 711 shared, 153 API-client, 2,599 core, and 451 mobile tests
